Manchester United confirmed over the weekend that Sam Mather had finally completed his long-awaited move to Kayserispor.Back in the summer, the midfielder had been on the verge of joining the Turkish outfit until the deal fell through at the 11th hour.Mather was left feeling aggrieved at the fact he’d be spending another five months playing academy football, but bided his time in preparation for the January window. ℹ️ #MUAcademy forward Sam Mather has joined Turkish side Kayserispor on a permanent deal.

If not, he is a firm target for AS Roma.
